To all 'whom it may concern.'

Be it own that I, Moirriium S. PARK' mm., a citizen of the United States, and a resident of Littleton, county of Arapahoe,

- I State of Colorado, have invented a certain Mounting, of which the following is a speciication accompanied by drawings. Y

This invention relates to mountings and particularly lto a mounting `for hoists or l0 other machines which is adapted to be bolt-v ed down toa dat surface, such as the platform of a mine car, stone boat or other vehicle or an a timber structure or support, so that it sh l have the capacity of oscillation ll about its perpendicular axis. o l

Small air driven hoists, for instance, of which the so called little tugger isa well knownexampleare used for man y lifting, hauling and handling jobs. Miners use $0 them in arvariety of ways, clamped to va'- rious forms of supports for lowering, rais-fY ing, hauling dragging, and numerous other purposes. hey are also used, among other places, on board ship, in structural steel 2l work, in manufacturing and4 power plants and 1n fact in every placevwhere a small compact powerful unit is desired.

In using such hoists or in fact in usino` almost any machine adapted to be mounted 80 by means of clamps, occasions arise in which it becomes necessary or desirable to-change the operative position or adjustmentof the device in the working plane. Y

The objects of the present invention are 85 to enable a hoist or other device to be quickly changed and adjusted at will to any position in the working plane by the simple expedient of rotation, the mounting being of few parts and readily assembled and 4e, disassembledj rugged'in character; and specifically in the case of thel application of a hoist as above mentioned, to enable the mounting to be bolted down to the door of fa mine car, stone boat or other base and 45 quickly andeasily rotated in order that the rope may be led oi straight fromthe dru'm in any direction in the `working plane. l Y To hese and other ends, which will hereinafter appear, .the invention is shown in one' 5o 'ofvits preferred forms in the accompanying draw-'ings,inwhich. Figure 1 is a sideselevation partly in lon.

gitudinalvertical'. section, showing a little tugger hoist for` illustrative purposes mounted longitudinally on a Atimber platform orv base by means ,of my' mounting; taken o n'the line l-lof Figure 2; Y Figure 2 is a top plangview of the mounting partly in section, taken on the line 2 2 of Figure 1;

Figurey 3 is a detail transverse Sectional view through one end of theV mounting, taken on the line v#Bt-#3 of Figure 2; F igiene 4 visa perspective view of the cone mem r or' swivel form-ing a. part of the mountin l -f y v Referring to the drawings, a base or sup- A is shown, partly roken away, to which the base-plate B. of 'the mounting is adapted to be secured by means of bolts (not shown) adapted to pass through the holes `C locatediat A the four corners of the plate Bs A stationary abutment member D is formed on rthebase plate 13 ap roximately centrally thereof, this abutment bein undercut, forming an opensemi-circular ared recess E, and being' referably reinforced by means of aplurality. of ribs F, lformed integrally therewith and joining theend of base plate B,

' A lmovable clamping member Gv-is slidably mounted on the base plate B at its oposite end, thismovable clamping having a portion H rejecting centrally thereof. The portion is undercut at` the mounted to slide free y ngit'udinally in member G is Y o member the base plate B toward and away from the abutment member D, having for this'pur- I pose, a longitudinal Vflanged web K' which is adapted to slide in a corresponding groove L in the raised central portion vO of the base miA plate B. Sliding movement of the clamp# lng member G is eiected by apluralit of side rods' or bolts l having heads Q, It ese heads fitting in undercut sockets'R at the end of the clamping member G, Vthe bod gitudiiial recesses 'S in the under side of the portions of the bolts passing .through len:` o9 v clamping member G, through Vholesfl. at the outer sidesf the abutment meinberD Y es .lend to form a,semi-circular iiared recess J j Q3 esta and thence through ears U uprising from the base plate B at its lop osite end where screw threaded means in t e form ci a plurality of nuts V 'are employed to move the rods longitudinally andfsecure the clamping member G in position against the artic be clamped. i

For a portion of their length adjacent to the clamping member Gf the bolts traverse longitudinal supporting and idin ribs W formed on the base p ate in a with the recesses S.

A swivel X, forms a part of the mounting, but also, necessaril ,becomes a part of the hoist or other mac ne to be mounted. This swivel X includes a circular cone base Y and a plate Z.- The hoist or otherm'a'- chine a; Iis bolted t9 the plate -Z by bolts b passing through holes 'd in the plate Z and the cone base Y ilts within the undercut semi-circular recesses E and J of the members D and G respectively, and rests upon the base plate B.. The base plate B is cut away at this point, indicated at e, t5\reduce the friction and facilitate rotation of themachine mounted on the swivel X. rThe longitudinal recesses S'and holes through which the side rods P pass are in substantially the, same plane as the undercut reowerful clamping on the cone base of the swivel is obtains By means of this form of mounting rotation of the machine in the working plane is permitted in any direction and. to any deee. Whenthe desired position has beenv et'erinined the nutsli are tightened, slidingA the clamping member G toward the. abutment D, clamping the cone disk Y securely between them.

. The deviss disassembled with facility,

removal of the cotter pins f and nuts Y permittin the member- G to slide out of the i base p ate B, whereupon the rods F readily drop out of the undercut recesses S, the base -v plateBremaining secured to the support A.

It will be noted that the hoist a extends laterally beyond the swivel Z and its cone base Y. The hoist a extends also laterally over the greater part of the baise plate B.

For the sake of accessibility, the ears U are located a convenient distance beyond the lateral limit of the hoist a and the bolts" P are made correspondingly long to extend through the ears U, so that, the nuts V may beturned without the use of a spe ial wrench. This arrangement adds to the fa; cility with which the hoist a'inay be adjusted on the base B.
